The main objective of this study was to investigate the booster antibody response in individuals with initially high levels of diphtheria antitoxin. Sixty individuals eligible for the routine booster by the age of 18 years each received a single dose of 5 Lf of diphtheria toxoid in diphtheria-tetanus vaccine. A double antigen ELISA was used for the assessment of the antibody levels. Chaotropic ...

Serogroup B Neisseria meningitidis (MenB) is a major cause of invasive disease in early childhood worldwide. The only MenB vaccine available in Brazil was produced in Cuba and has shown unsatisfactory efficacy when used to immunize millions of children in Brazil. In the present study, we compared the specific functional antibody responses evoked by the Cuban MenB vaccine with a standard vaccine...

Recommendations for routine vaccinations in children and adolescents have changed multiple times in recent years, based on findings in clinical trials, licensure of new vaccines, and evidence of waning immunity. Despite the overwhelming success of vaccinations, vaccine delay and refusal are leading to pockets of vaccine-preventable diseases. Schedules for diphtheria and tetanus toxoids, and ace...

We evaluated the immunogenicity and reactogenicity of diphtheria, tetanus, whole-cell pertussis and hepatitis B (DTPw-HB) combination vaccine manufactured by Shantha Biotechnics Pvt Ltd, Hyderabad, India in healthy infants between 6 and 8 weeks of age. Overall 123 infants (male:female ratio, 1:1.3) were recruited, of which 112 received all three doses of the vaccine at 6, 10 and 14 weeks of age...

OBJECTIVE To evaluate the immunogenicity and safety of a pentavalent (diphtheria, tetanus, acellular pertussis, inactivated poliovirus, Hib polysaccharide-conjugate) combination vaccine booster dose. DESIGN Multicenter, open, Phase III clinical study. SETTING Two tertiary-care hospitals in Delhi and Vellore, India. PARTICIPANTS/PATIENTS 207 healthy Indian children. INTERVENTION The DTaP...

In October 2011, a child who had arrived in Sweden from Somalia presented with atypical tonsillitis, was treated with penicillin and the symptoms resolved. A throat swab was positive for toxigenic Corynebacterium diphtheriae. The child's family were then vaccinated with diphtheria, tetanus and pertussis vaccine and screened for C. diphtheriae. No secondary cases were found. A high level of adhe...

The IAP Committee on Immunization (COI) recommends offering Tdap vaccine instead of Td/ TT vaccine in all children / adolescents who can afford to use the vaccine(1). Tdap is a costly vaccine, which many parents may not be able to afford. There is a need for a less expensive vaccine, though slightly more reactogenic because of whole cell pertussis antigen in reduced quantity, with full dose of ...

PURPOSE To assess the immunization status of young children in a predominantly Hispanic region in and around downtown Los Angeles, and factors associated with complete immunization by age 24 months. METHODS The information was gathered in a two-stage cluster survey with probability proportionate to estimated size (PPS) sampling of 30 clusters at the first stage, and simple random sampling of ...

OBJECTIVE To determine long term outcome in children who had a severe acute neurological illness in early childhood associated with pertussis immunisation. DESIGN Follow up study of cases and matched controls. SETTING Assessment of children at home and at school throughout Britain. SUBJECTS Children recruited into the national childhood encephalopathy study in 1976-9 were followed up, wit...

BACKGROUND Current political crises in the Middle East and economic discrepancies led millions of people to leave their home countries and to flee to Western Europe. This development raises unexpected challenges for receiving health care systems. Although pan-European initiatives strive for updated and optimized vaccination strategies, little data on immunity against vaccine-preventable disease...
